Stretchy Universe

Thewhole universe isn't expanding... just bits of it.

Was thinking about the whole "rubber sheet" description of matter, like metal balls on a rubber sheet. And so I was thinking, what if the sheet kept "bending"... like putting a bowling ball in a rubber sheet, it makes a well (the gravity well), except that the sheet keep stretching deeper and deeper around the ball.

So if you look at an object far away, it is redshifted as if the whole universe is moving away, when really its the local universe that is moving away.

This would also explain quasar multiple light-speed red shifts, if for some reason the space there was moving away more than the hubble constant, it would appear to be red shifted more.

Silly halfbaked idea.

It's in the Au Jus Martini.
Haven't you been paying attention?

       so black holes aren't massive, they've just been around the longest in the same place ?
FlyingToaster, Jul 23 2009

       Thing is, FlyingToaster, that yes - that is kind of true. Since time dilates under acceleration, there is a point within (indeed, an area around) a black hole for which a moment will take the entire length of the universe to unfold - the same goes with the red-shift phenomena, since the universe is believed to consist of spacetime, the red-shift we see is also evidence of time stretching as well.   

       Furthermore, if spacetime can be seen to form into curved arrangements due to the presence of mass and if mass and energy are interchangeable AND if spacetime does NOT tend to curve around energy - then we might conclude that spacetime itself is not just the arena in which matter and energy operate, but that it is fundamentally the very same thing - which in turn further supports the locality of spacetime i.e. that different portions of it will have different local properties - most likely dependent on the measurable amount of mass and energy present.   

       IF matter, energy and spacetime are tripartite - and e=mc² would suggest that they are (since the term c² is only definable in terms of spacetime) then the mysterious matters dark might turn up curled up in spacetime somewhere.   

       The Hubble Constant is an approximation based on taking a statistical sample over a huge and wide-ranging area (The Entire Visible Universe) and I think it's perfectly reasonable to assume that it's an amalgamation of lots of local values.

       If this will make me taller in some parts of the universe then I'm all for it. Maybe it wouldn't go so far over my head that way...

       funny I always imagined you as very tall, Ray.   

       so if you fell into a black hole, you'd experience it for quiiiite a while... wonder if you'd get very hungry.

       Trouble is po, you wouldn't notice, but looking back out at the universe, everything would appear to speed up to the extent that you'd be able to see the stars winking in and out of existence, whole galaxies swirling into one another and eventually the end of everything altogether - so it might be best to bring a packed lunch.

Or book a table at Milliways.

       Nah --- it is just field free wave attenuation...   

       That is --- After a few billion odd miles of going up and down really fast the little photon goes a bit red with all the exertion...   

       All that needs to be shown is that high frequency waves carry more information than low frequency waves (and that is clearly the case). And...   

       --- either, information must be lost in transmission (the probability of losing information tends to 1 with time)
--- or, entropy of an isolated photon must increase (... not sure ...)

       Me, the tall, dark, and handsome type? That's a bit of a stretch. Only 5'10" with the shoes off. My wife is taller.

       I always pictured you posed on the cover of a dime store paperback, in a tux, with a gun and a leggy blonde

       perhaps RS hails from the land of the giants.

       //So if you look at an object far away, it is redshifted as if the whole universe is moving away,//   

       The problem is that your theory puts the earth in a special location--smack in the middle of the expansion. Otherwise the expansion wouldn't look uniform in every direction.

       Not at all - since all bodies would be falling away, sitting on ANY body would look the same.. they all stretch through.

       I'm 6'2'' and so is my Dad. I've had a dog for 10 years and she can run a mile. there's 36 windows on my house and my car was built in 1992. I can bend in 56 ways and I have lived for 12 thousand days. In my town people talk more about people than about ideas. I once pooped in my underwear during class and instead of running home I just washed them out in the sink. I hate bread, but love sourdough pretzels. They're probably good for you because they don't really taste like anything. I had a job once and it was very cool, and if you give me the opportunity to talk about it I will. If you don't, I still will.
